Abstract
A method and apparatus for cleaning an interior cavity of a container including the following described steps. Firstly, insert a hard pliant card with rapid elastic recovery to within 96% of original into an interior cavity of a container. Secondly, exert a force upon the card until the card deforms to assume an arcuate shape substantially conforming with the interior contours of the container. Thirdly, move the card along the interior contour of the container in a scraping action such that an edge of the card scrapes residue from the interior contour of the container.
Claims1
A scraper, comprising:
- a hard pliant rectangular card with three scraping edges and a beaded gripping edge having axial contouring on a plane coincident with the card thereby forming an arcuate indent, the card being of polymer plastic material sufficiently pliant to conform to a one inch radiused curve and to a substantially 90 degree corner with rapid elastic recovery to within 96% of its original shape.
